The Borderlands 4 endgame opens after level 72 and a True Vault Hunter Mode campaign clear. It consists of four main systems: UVHM Ranks (scaling difficulty and loot), Nightmare Rifts (instanced loot farming), Moxxi's Encore (weekly boss rush), and Guardian Rank (account-wide XP progression). This guide breaks down each system's numbers and the optimal progression order.
Ultimate Vault Hunter Mode (UVHM), Rank 1 to 5
UVHM unlocks after completing TVHM at level 72. Unlike BL2's UVHM, it is a ranking system rather than a difficulty mode: each rank increases enemy stats and loot quality, and each rank stacks on the previous one.
UVHM Rank Scaling:
| Rank | Enemy Health | Enemy Damage | Loot Quality |
|---|---|---|---|
| Rank 1 | +50% | +25% | +2 Mayhem equivalent |
| Rank 2 | +100% | +50% | +4 Mayhem equivalent |
| Rank 3 | +175% | +80% | +6 Mayhem equivalent |
| Rank 4 | +275% | +120% | +8 Mayhem equivalent |
| Rank 5 | +400% | +175% | +10 Mayhem equivalent (≈ Mayhem 20 gear) |
How to rank up: Each rank requires a set number of Proving Grounds completions. Rank 1 needs 10, Rank 2 needs 25, Rank 3 needs 50, Rank 4 needs 100, and Rank 5 needs 200 — 385 total runs. Each run takes 5–12 minutes depending on build and map.
Is UVHM worth it? Rank 3 is the sweet spot for casual players: the +6 Mayhem loot jump is significant without the exponential difficulty of Ranks 4–5. Rank 5 is for min-maxers — Rank 5 exclusive rolls can drop items with 3 anointment slots instead of the standard 1, which stack multiplicatively.
Nightmare Rifts, Endgame Instances
Nightmare Rifts are instanced content accessed from the Rift Station on Sanctuary III. They function like Diablo 3's Greater Rifts: procedurally generated combat arenas with scaling difficulty and a timer. Each Rift has a Paragon level from 1 to 100; higher Paragons drop better loot.
Rift Mechanics: Each Rift spawns 5 waves of enemies followed by a boss wave, with a 15-minute timer. Enemies gain +8% health and +4% damage per Paragon level. At Paragon 50 and above, enemies gain random Affixes:
- Elemental Enrage — all attacks apply a random element.
- Vampiric — enemies heal for 10% of damage dealt.
- Teleporting — enemies teleport on hit.
- Shielded — enemies are immune to damage while their shield is active.
Rewards: Each completion grants Rift Orbs (currency for the Rift vendor) and a guaranteed legendary based on Paragon level: Paragon 1–30 gives 1, 31–60 gives 2, 61–80 gives 3, and 81–100 gives 4 legendaries. The Rift-exclusive weapon pool (Nightmare Spire sniper, Riftwalker SMG, Void Edge shotgun) has roughly 9% drop rates from the completion reward.
Optimal Farming: Paragon 30 is the most efficient farm — 2 legendaries per 8–12 minute clear with manageable scaling. Paragon 60+ runs take 15+ minutes and their affix mechanics can wipe unoptimized groups. Farm Paragon 30 for Orbs and general loot, then push Paragon 100 for exclusive weapons with a full build and a coordinated group.
The Rift vendor sells exclusive anointments with Rift Orbs (20 Orbs per roll). The Consecutive Hits +2% anointment is among the highest-value purchases, worth more than most individual legendary weapons.
Weekly Events, Moxxi's Encore
Moxxi's Encore launches every Thursday at 9 AM Pacific / 12 PM Eastern. It is a weekly boss rush mode with unique modifiers and exclusive rewards.
Format: Moxxi's Encore pits you against 5 randomly selected bosses fought back to back with no save point between fights — going down on boss 3 restarts from boss 1. Each boss has a Moxxi Modifier:
- Moxxi's Tipsy — enemies leave elemental puddles on death.
- Moxxi's Lucky Break — enemies have 25% crit chance against you.
- Moxxi's Party — random loot tinks spawn during the fight.
Rewards: Clearing all 5 bosses grants Moxxi Tokens for the Encore vending machine. Token rewards scale with difficulty: Normal gives 5, Mayhem 6 gives 15, Mayhem 10 gives 30. The machine sells exclusive cosmetics, Moxxi class mods (about 7% drop chance per token roll), and a weekly Moxxi's Special — a curated legendary with guaranteed god-roll parts.
Strategy: The no-save-point constraint rewards survivability over raw DPS. Amon's Phalanx Mode and Rafa's dual turrets provide consistent damage without requiring perfect play. Bring one weapon of each element, since the encounter pool includes all base-game bosses and elemental coverage is mandatory.
XP Farming, 300k+ XP Per Hour
Guardian Rank is the account-wide progression system that persists across all characters. Each level requires roughly 50,000 XP at low levels, scaling to 200,000+ XP at high levels, with a max Guardian Rank of 500.
Route 1: Scraptrap Nest (Levels 13–65) — 10–15 levels per hour, located in the Compactor Trashlantis from the Handsome Jackpot DLC. Waves of scraptraps spawn infinitely without save-quitting; XP per kill is 120–180 base, scaling with Mayhem level.
Route 2: Slaughter Shaft (Levels 65–72) — 8–12 levels per hour, 5 rounds of 4–5 waves each, 12,000–18,000 XP per round. With Moxxi's Endowment (+15% XP) and Borderlands Science (+25% XP), this reaches about 300,000 XP per hour at Mayhem 10.
Route 3: Graveward Boss Farming (Guardian Rank) — 6–10 levels per hour after max character level. Each kill awards about 4,000 XP at Mayhem 10 with XP boosts; kill time is 10–20 seconds with an optimized build, for 180,000–300,000 XP per hour.
Route 4: Circle of Slaughter, Cistern of Slaughter (Guardian Rank 400+) — on Promethea, averaging 350,000 XP per hour at Mayhem 10. The final wave boss Uranus drops additional legendaries. Requires good crowd control or you'll get swarmed.
XP Boost Stacking: Moxxi's Endowment artifact (7–15% XP), Borderlands Science boost (25%, 500 points, 2 hours), and a class mod with +Guardian Rank XP anointment (up to 10%) stack to 50% bonus XP. This reduces the time to Guardian Rank 500 from about 80 hours to 53 hours.

Key Features of BL4 Endgame
- UVHM Rank Progression — 5 difficulty ranks; Rank 5 gives Mayhem 20-level loot. 385 Proving Grounds runs total to max rank.
- Nightmare Rift Paragon System — 100 Paragon levels, +8% enemy health and +4% damage per level. Paragon 30 is the best time-to-reward sweet spot.
- Weekly Moxxi's Encore — 5-boss rush with randomized modifiers, exclusive cosmetics, and a guaranteed god-roll legendary as the weekly special.
- Triple Anointment Drops — Rank 5 exclusive items can roll 3 anointment slots, estimated 1 in 300 Rank 5 drops.
- Rift Orbs — earned from Nightmare Rifts, exchanged at the Rift vendor (20 Orbs per roll). Best anointments: Consecutive Hits +2% (50 Orbs), While Action Skill Active +80% Elemental Damage (40 Orbs).
- Moxxi Tokens — earned from Moxxi's Encore, spent at the Encore machine. Tokens expire at the next weekly reset.
- Guardian Rank 500 — grants about 35% bonus gun damage, 25% bonus shield capacity, and 20% action skill cooldown reduction. Prioritize the Damage tree first.
- Proving Grounds Rotation — 12 maps with different factions and hazards. The daily challenge awards double rewards and counts as 2 completions toward UVHM rank.
Best Use Cases
Weekly Reset Plan: Run Moxxi's Encore first on Thursday (tokens expire), then the daily Proving Grounds challenge for double rewards, then farm Nightmare Rifts for Orbs, and spend Thursday evening on UVHM progression.
New Character Gearing: Farm Moxxi's Encore on your main for the weekly special weapon, then pass it to an alt through the shared bank — a god-roll weapon at level 72 trivializes the leveling process.
Rift Orb Farming: Farm Paragon 30 solo with a C4SH card build. Each clear takes 8–10 minutes and awards 15–20 Orbs, for roughly 100 Orbs per hour — enough for 2 exclusive anointment rolls.
Endgame Progression Tips
- Prioritize UVHM Rank 3 before Nightmare Rifts — the +6 Mayhem loot jump makes Rift farming significantly faster.
- Do the daily Proving Grounds challenge every day; it counts as 2 completions toward rank, saving about 49 runs (8–10 hours) over the full grind.
- Spend Moxxi Tokens immediately — they expire at the next weekly reset. Buy class mods first for their long-term anointment value.
- Save triple-annointed drops even with bad rolls; three mediocre anointments beat one perfect anointment because the numbers stack multiplicatively.
- Keep a full elemental weapon set (shock, corrosive, incendiary, cryo) for Nightmare Rifts — random enemy compositions can hard-counter a single-element loadout.
